Yup. Well, there's a den under the viewing area at the back of shot but I suspect they don't have access during the day. What's frustrating is that it wouldn't be too bad if it was properly furnished, but just that one column of climbing leaves it looking a bit of a joke. A shame, as the outside enclosure is fine and the rest of the tropical house is very nice.
It's home to 1.1 White-cheeked Gibbon, incidentally.
